Description

The present invention relates to an electronic component (hereinafter, "parts" and referred) board production machine for producing the board mounted is board production line comprising a plurality of board production machine to share the production of the board, and board production line Regarding the line management device applied to.

As a board production machine that produces a board on which a large number of parts are mounted, there are a solder printing machine, a component mounting machine, a reflow machine, a board inspection machine, and the like. It has become common to connect these board production machines to construct a board production line. Furthermore, in many cases, a line management device for managing the progress of production is attached. Generally, when switching the type of substrate (board type) produced on the substrate production line, it is necessary to change the production job data in each substrate production machine. The production job data describes the detailed specifications of the production operation of the board production machine. The production job data differs for each type of substrate production machine and also for each type of substrate. Patent Document 1 discloses a technical example relating to a method of managing production job data when switching substrate types.

The production control device of Patent Document 1 has no production record by referring to the means for editing the NC program (production job data), the means for transmitting the NC program to the component mounting machine, and the production record flag provided in the NC program. It is provided with a means for notifying the operator and inquiring whether or not transmission is possible when the determination is made. According to this, it is possible to prevent the production of defective products unintended by the operator due to the data change of the NC program.

By the way, the order of the substrate types to be produced is devised by the production manager and distributed to the relevant departments in the form of a production plan. Alternatively, the order of the substrate types to be produced is transmitted online to the relevant departments in the form of production planning data. The worker refers to the production plan or the production plan data, and sets the type of the substrate to be produced in the next and subsequent stages (the substrate type in the next and subsequent stages). At this time, a manual selection operation is performed by the operator, or an automatic selection function is used. In the case of the manual selection operation, the operator refers to the production plan and the production plan data, and selects and operates the data corresponding to the next and subsequent board types from the plurality of production job data.

Here, the names of a plurality of production job data are often similar to each other, and there is a risk that the operator may erroneously select them. Further, when separate production jobs are defined for the front surface and the back surface of one substrate, there is a possibility that the operator may mistake the front surface and the back surface. Further, even if the production job data of the same board type, there may be a plurality of production job data having a change history. In this case, there is a risk of erroneously selecting production job data other than the latest revision. Also, if the latest revision is prohibited for some reason, the worker may not be able to select the production job data of the old revision that should be used.

On the other hand, the production plan can be changed. For example, a substrate type that has been requested to be produced by a limited express is incorporated by interrupting the initial production plan. Further, for example, if the procurement of parts is delayed, the production order of the board type on which the parts are mounted is postponed. Such a change in the production plan is notified to the worker by notifying the change of the production plan or updating the production plan data. However, the worker may not be able to grasp the change in the production plan due to the time delay of the notification or the like, and may set the wrong board type after the next time.

Considering the above-mentioned artificial setting error and change in production plan, the technique of Patent Document 1 cannot determine whether or not the setting of the substrate type is correct from the next time onward. In addition, even if the board type is correct after the set one, the actual production will not start unless the production conditions are satisfied. In this case, there is room for change in the production plan. For example, when temporary maintenance is required for a certain board production line, it is possible that the set next and subsequent board types are diverted to another board production line.

If production is started with the setting of the substrate type after the wrong one, a large loss will occur due to an erroneous production or a delay in the production completion time. Moreover, even if it is noticed before the start of production, the setup change work performed corresponding to the wrong board type is wasted.

This specification describes a board production machine, a board production line , and a line management device that can deal with artificial setting errors and changes in production plans, and can start production after confirming that the set next board type is correct. Providing is an issue to be solved.

In the present specification, the board type setting unit that sets the next board type to be produced next to the current board type currently being produced based on the code information of the board, and the above-mentioned setting unit based on the code information of the board. A substrate type confirmation unit for confirming whether or not the next substrate type is correct, a production condition investigation unit for investigating whether or not the production conditions for producing the substrate of the next substrate type are satisfied, and the next substrate type A substrate production machine including a production permission unit that permits production of the substrate of the next substrate type when the production conditions are correctly satisfied is disclosed.

In addition, in this specification, "the next and subsequent substrate types to be produced after the next" are only the case of "the next substrate type to be produced next" and two types including "the next substrate type to be produced next". In the case of the above substrate types, both are meant.

Further, the present specification includes a plurality of board production machines that share the production of boards and a line management device, and the line management device is the next board type to be produced next to the current board type currently being produced. A board type setting unit that sets the following based on the code information of the board, a board type confirmation unit that confirms whether or not the set next board type is correct based on the code information of the board, and the next board. When the production condition investigation unit which investigates whether or not the production condition for producing the seed substrate is satisfied, and when the next substrate type is correct and the production condition is satisfied in all the substrate production machines. Discloses a substrate production line comprising a production permit unit that permits the production of the substrate of the next substrate type.
Further, this specification is a line management device applied to a board production line composed of a plurality of board production machines that share the production of boards, and is produced next to the current board type currently being produced. A board type setting unit that sets the board type based on the code information of the board, a board type confirmation unit that confirms whether or not the next board type that has been set is correct based on the code information of the board, and the above. The production condition investigation unit for investigating whether or not the production conditions for producing the substrate of the next substrate type and the production conditions for producing the next substrate type are correct and the production conditions are satisfied in all the substrate production machines. In this case, a line management device including a production permission unit that permits production of the substrate of the next substrate type is disclosed.

According to the substrate production machine disclosed in the present specification, it is confirmed whether or not the set next substrate type is correct, and whether or not the production conditions are satisfied is investigated, and the next substrate type is correct and the production conditions are correct. Allow production of substrates if met. Therefore, if the set next board type is incorrect, the production of the board is not permitted. In addition, if the production conditions are not satisfied even if the set next board type is correct, the production of the board is not permitted because there is a possibility of changing the production plan, in other words, there is room for changing the next board type. .. Therefore, it is possible to deal with artificial setting errors and changes in the production plan, and it is possible to start production after confirming that the set next board type is correct.

In the substrate production line and the line management device disclosed in the present specification, permission and disapproval of substrate production are determined in the same manner as in the above-mentioned substrate production machine. Therefore, it is possible to deal with artificial setting errors and changes in the production plan, and it is possible to start production after confirming that the set next board type is correct.

It is a figure which showed typically the structure of the substrate production line of an embodiment.

(1. Configuration of substrate production line 1 and substrate production machine of the first embodiment)
The substrate production machine of the first embodiment will be described with reference to FIGS. 1 to 3. FIG. 1 is a diagram schematically showing the configuration of a substrate production line 1 including the substrate production machine of the first embodiment. The board production line 1 is composed of five board production machines that share the production of boards. Specifically, the board production line 1 is configured by arranging a solder printing machine 12, a printing inspection machine 13, a component mounting machine 14, a board appearance inspection machine 15, and a reflow machine 16 in a row.

The five board production machines are communicated and connected to each other using the communication line 29. Further, the five board production machines are communication-connected to the administrator terminal 6 using the communication line 29. Two-way communication is possible between the board production machines and between the board production machines and the administrator terminal 6. The manager terminal 6 is used by the production manager. The production manager formulates and changes a production plan for a plurality of substrate types produced on the substrate production line 1. The production manager further notifies the relevant departments of the production plan and promotes the execution of the production plan.

The solder printing machine 12 prints paste-like solder on a substrate in a predetermined pattern shape. The solder printing machine 12 and the printing inspection machine 13 are connected by a substrate transfer device 22. The printing inspection machine 13 inspects the solder printing state of the conveyed substrate. The printing inspection machine 13 and the component mounting machine 14 are connected by a substrate transfer device 23. The component mounting machine 14 mounts components on the solder of the conveyed substrate. The component mounting machine 14 and the board appearance inspection machine 15 are connected by a board transfer device 24.

The substrate appearance inspection machine 15 inspects the appearance state of the parts mounted on the conveyed substrate. The board appearance inspection machine 15 and the reflow machine 16 are connected by a board transfer device 25. The reflow machine 16 remelts the solder of the substrate determined to be normal by the substrate appearance inspection machine 15 and then solidifies it to stabilize the connected state. This ends the production of the substrate. The configuration of the substrate production line shown in FIG. 1 is an example, and may be a line configuration of various known forms, for example, a line configuration including a plurality of component mounting machines.

The solder printing machine 12, the printing inspection machine 13, the component mounting machine 14, and the substrate appearance inspection machine 15 can all be the substrate production machines of the first embodiment. Hereinafter, the description will proceed by taking the case where the component mounting machine 14 is the substrate production machine of the first embodiment as an example. The component mounting machine 14 includes a control unit 4 that controls a component mounting operation. The control unit 4 also operates when switching the substrate type to be produced. FIG. 2 is a diagram for explaining the functional configuration of the control unit 4 of the component mounting machine 14 which is the substrate production machine of the first embodiment.

As shown, the control unit 4 has a display unit 48 and an input unit 49. Further, the control unit 4 has four functional units, a substrate type setting unit 41, a substrate type confirmation unit 42, a production condition investigation unit 43, and a production permission unit 44. The board type setting unit 41 holds a plurality of production job data (JOB1, JOB2) in the memory device 45. The memory device 45 may be an internal device of the component mounting machine 14, or an external device shared by a plurality of board production machines. The board type confirmation unit 42 performs bidirectional communication with the administrator terminal 6. The detailed functions of the four functional parts will be described in detail later in the description of the operation and the operation.

The production job data (JOB1, JOB2) is data that describes detailed specifications regarding the mounting operation of parts. The production job data (JOB1, JOB2) is different for each substrate type. The production job data (JOB1, JOB2) is given a data name and update history information. As the update history information, the number of revisions, which means the number of updates, and the update date can be exemplified. A plurality of production job data having the same data name but different update history information are interpreted as different data.

For example, the data name is "JOB1", the number of revisions is "R0", "R1", "R2", and "X3", and both can be concatenated with "_". In this case, there are four production job data, "JOB1_R0", "JOB1_R1", "JOB1_R2", and "JOB1_X3". Here, the first letter R of the number of revisions represents the availability, and the first letter X represents the prohibition of use. The second letter number of the number of revisions indicates the number of updates. Then, it is stipulated that the number of revisions with a large number of updates is preferentially used. Therefore, in this example, only "JOB1_R2" can be used as the production job data, and the others cannot be used.

Three unusable production job data, that is, "JOB1_R0", "JOB1_R1", and "JOB1_X3" are held in the memory device 45 in consideration of the purpose of confirming the changed part at the time of update and the possibility of future use. NS. Therefore, the memory device 45 contains both usable production job data and prohibited production job data. Therefore, the worker may mistakenly select the production job data.

(2. Operation and operation of the substrate production machine of the first embodiment)
Next, the operation and operation of the component mounting machine 14 will be described focusing on the operation of the control unit 4. FIG. 3 is a diagram of a processing flow for explaining the operation of the control unit 4 of the component mounting machine 14 which is the substrate production machine of the first embodiment. In step S1 of FIG. 3, the board type setting unit 41 of the control unit 4 operates to set the next and subsequent board types to be produced after the current board type currently being produced.

More specifically, the board type setting unit 41 displays a list of data names and update history information of a plurality of production job data (JOB1 and JOB2) on the display unit 48, and requests the operator to perform a manual selection operation. After confirming not only the data name but also the update history information, the operator selects and operates the production job data corresponding to the board type from the input unit 49. The board type setting unit 41 selects the production job data according to the selection operation. As a result, the setting of the board type is completed from the next time onward.

In step S2, the board type confirmation unit 42 operates following the board type setting unit 41. After the production of the substrate of the current substrate type is completed, the substrate type confirmation unit 42 inquires the production manager of the next and subsequent substrate types set by the substrate type setting unit 41 and confirms whether or not the substrate type is correct. Since the production plan is often changed during the production of the current substrate type, the substrate type confirmation unit 42 does not operate.

Specifically, the board type confirmation unit 42 notifies the administrator terminal 6 of the data name and update history information of the production job data corresponding to the board type from the next time onward, for example, by e-mail. Alternatively, the board type confirmation unit 42 displays the data name and update history information of the production job data on the display unit 48. The production manager compares the data name and the update history information with the latest production plan, and if even one character is different, it is judged as an error, and if it is an exact match, it is judged as correct. The production manager replies the inquiry result, that is, the correctness of the board type from the next time onward, by replying to an e-mail or inputting from the input unit 49.

In the next step S3, the substrate type confirmation unit 42 confirms the inquiry result, and if the substrate type is incorrect from the next time onward, the execution of the processing flow proceeds to step S4. In step S4, the board type confirmation unit 42 displays the board type change request on the display unit 48 from the next time onward, and returns the execution of the processing flow to step S1. The worker who recognizes the change request investigates whether or not the production plan has been changed, and also investigates his / her own setting error. Then, in the second step S1, the worker selects and operates the production job data again based on the survey result.

In addition, the production manager may answer the correct next and subsequent board types when the inquired next and subsequent board types are incorrect. In this case, in the second step S1, the substrate type setting unit 41 can set the correct next and subsequent substrate types based on the answer of the production manager.

If the substrate type is correct in step S3 and thereafter, the substrate type confirmation unit 42 advances the execution of the processing flow to step S5. In step S5, the production condition investigation unit 43 operates following the substrate type confirmation unit 42. The production condition investigation unit 43 investigates whether or not the equipment condition that the production of the substrate of the substrate type can be started is satisfied. The production condition investigation unit 43 investigates the in-flight condition and collects information on the equipment conditions.

In the next step S6, the production condition investigation unit 43 determines the equipment condition, and if it is not satisfied, the execution of the processing flow proceeds to step S7. In step S7, the production condition investigation unit 43 displays a warning display on the display unit 48, and proceeds to the execution of the processing flow in step S8. The operator who recognizes the warning display performs a return procedure on the component mounting machine 14. Then, after the equipment conditions are satisfied, the operator inputs a restart command from the input unit 49.

In step S8, the production condition investigation unit 43 waits for the input of the restart command. When the restart command is input, the production condition investigation unit 43 returns the execution of the processing flow to step S1. If the worker's return procedure is short, the production plan is rarely changed. However, if the return procedure takes a long time, the production plan is often changed. Therefore, in step S1 returned, the worker investigates whether or not the production plan has been changed, and then selects and operates the production job data again.

When the equipment condition is satisfied in step S6, the production condition investigation unit 43 advances the execution of the processing flow to step S9. In step S9, the production permission unit 44 operates following the production condition investigation unit 43. The production permission unit 44 permits the production of the substrate of the substrate type from the next time onward. As a result, the processing flow of the control unit 4 ends. Subsequently, the setup change work corresponding to the substrate type is performed from the next time onward, and the production is ready. Subsequently, the component mounting machine 14 starts production of substrates of the substrate type from the next time onward.

(3. Aspects and effects of the substrate production machine of the first embodiment)
The component mounting machine 14, which is the board production machine of the first embodiment, includes a board type setting unit 41 for setting the next and subsequent board types to be produced after the current board type currently being produced, and the set next and subsequent boards. The substrate type confirmation unit 42 that confirms whether or not the seeds are correct, the production condition investigation unit 43 that investigates whether or not the production conditions for producing the substrate of the next and subsequent substrate types are satisfied, and the subsequent and subsequent substrate types are correct. And, when the production conditions are satisfied, the production permission unit 44 that permits the production of the substrate of the substrate type from the next time onward is provided.

According to this, if the board type is wrong after the set one, the production of the board is not permitted. In addition, if the production conditions are not satisfied even if the set board type is correct after the next time, the production plan may be changed, in other words, there is room for changing the board type after the next time, so the production of the board Is not allowed. Therefore, it is possible to deal with artificial setting errors and changes in the production plan, and it is possible to start production after confirming that the board type is correct after the set one. As a result, it is possible to prevent erroneous production due to the erroneous next and subsequent substrate types and delay in production completion time. In addition, unnecessary setup change work due to the wrong substrate type does not occur after the next time.

Further, the substrate type setting unit 41 is a plurality of production job data (JOB1, JOB2) used when producing a substrate of the substrate type from the next time onward, and is a plurality of production job data (JOB1, JOB2) different for each substrate type. Is retained, and the production job data corresponding to the board type is selected from the next time according to the manual selection operation. According to this, it is possible to set and confirm the board type from the next time onward by using the production job data different for each board type.

Further, the board type confirmation unit 42 confirms whether or not the board type is correct from the next time onward based on the data name of the production job data and the update history information given to the production job data. According to this, the production job Even if the operator makes a mistake in the setting due to a slight difference in the data name or update history information of the data, it is possible to reliably detect that the board type is wrong from the next time onward.

Further, the board type confirmation unit 42 inquires the production manager about the set next and subsequent board types, and confirms whether or not the board type is correct. According to this, since the production manager in charge of planning and changing the production plan is directly inquired, no error due to the change of the production plan occurs.

Further, the production condition investigation unit 43 investigates the equipment conditions in which the production of the substrate of the substrate type can be started from the next time onward. According to this, production is not permitted if the equipment conditions are not met. Therefore, if the production plan is changed after this, the substrate type can be reset from the next time onward.

(4. Configuration, operation, and operation of the substrate production machine of the second embodiment)
Next, the substrate production machine of the second embodiment will be mainly described as being different from the first embodiment with reference to FIGS. 4 to 6. FIG. 4 is a diagram schematically showing the configuration of a substrate production line 1A including the substrate production machine of the second embodiment. In the second embodiment, the line configuration itself of the substrate production line 1A is the same as that of the first embodiment. However, the solder printing machine 12A at the head of the line is the substrate producing machine of the second embodiment. The solder printing machine 12A includes a substrate type reading camera 27.

The substrate type reading camera 27 is arranged so as to face the substrate carry-in entrance 21, and images the upper surface of the substrate K mounted on the substrate carry-in entrance 21. Code information including information on the substrate type is attached to the upper surface of the substrate K. Therefore, the substrate type reading camera 27 can acquire the code information by performing image processing on the captured image. The solder printing machine 12A may include a code scanner capable of reading code information and operated by an operator instead of the substrate type reading camera 27.

Further, in the second embodiment, the administrator terminal 6 is not used. Instead, the solder printing machine 12A is communicatively connected to the schedule management server 71 using the communication line 29. The schedule management server 71 includes a production order management unit 72 and a personnel planning management unit 73. The production order management unit 72 manages the production order of the current substrate type currently being produced and the next and subsequent substrate types scheduled to be produced in the next and subsequent stages. In other words, the production order management unit 72 holds the execution order of the production job data of the current board type and the next and subsequent board types. The production manager changes the production plan by accessing the production order management unit 72 and rewriting the execution order of the production job data. The personnel plan management unit 73 manages the personnel plan of the worker in charge of the board production line 1A.

Further, the solder printing machine 12A is communicated and connected to the member management server 75 by using the communication line 29. The member management server 75 procures and manages the inventory of members used in the substrate production line 1A. The solder printing machine 12A includes a control unit 4A that controls the solder printing operation. The control unit 4A also operates when switching the substrate type to be produced. FIG. 5 is a diagram for explaining the functional configuration of the control unit 4A of the solder printing machine 12A, which is the substrate production machine of the second embodiment.

As shown, the control unit 4A has a display unit 48 and an input unit 49. Further, the control unit 4A has a substrate type setting unit 41A, a substrate type confirmation unit 42A, a production condition investigation unit 43A, and a production permission unit 44 as four functional units. The board type setting unit 41A holds a plurality of production job data (JOB1, JOB2) in the memory device 45. Further, the board type setting unit 41A controls the board type reading camera 27. The board type confirmation unit 42A performs bidirectional communication with the production order management unit 72. The production condition investigation unit 43A performs two-way communication with the personnel planning management unit 73 and the member management server 75. The detailed functions of the four functional parts will be described in detail in the description of operations and actions.

Next, the operation and operation of the solder printing machine 12A will be described focusing on the operation of the control unit 4A. FIG. 6 is a diagram of a processing flow for explaining the operation of the control unit 4A of the solder printing machine 12A, which is the substrate production machine of the second embodiment. In step S1A of FIG. 6, the substrate type setting unit 41A operates to set the next and subsequent substrate types to be produced after the current substrate type currently being produced.

More specifically, the substrate type setting unit 41A first sends an imaging command to the substrate type reading camera 27. When the operator places the first substrate K of the substrate type to be produced next on the substrate carry-in entrance 21, the substrate type reading camera 27 operates. The substrate type reading camera 27 takes an image of the substrate K, performs image processing to acquire code information, and sends it to the substrate type setting unit 41A. The board type setting unit 41A can recognize the board type of the board K based on the received code information. Further, the substrate type setting unit 41 can automatically select the production job data corresponding to the substrate type of the substrate K. This completes the setting of the next board type. In the second embodiment, the substrate type setting unit 41A sequentially sets the next substrate type, and does not set the next substrate type to be produced next.

In step S2A, the substrate type confirmation unit 42A operates following the substrate type setting unit 41A. The substrate type confirmation unit 42A confirms whether or not the next substrate type set by the substrate type setting unit 41A is correct after the production of the substrate of the current substrate type is completed. Specifically, the board type confirmation unit 42A inquires the production order management unit 72 of the production job data automatically selected by the board type setting unit 41A by communication, and confirms whether or not the data is correct. The production order management unit 72 determines whether or not the inquired production job data and the production job data held by the production order management unit 72 are correct or not based on whether or not the data names and update history information completely match. The production order management unit 72 replies the inquiry result, that is, the correctness of the next board type by communication. The production order management unit 72 may return the correct production job data when the inquired production job data is incorrect.

In the next step S3, the substrate type confirmation unit 42A confirms the inquiry result, and if the next substrate type is incorrect, the execution of the processing flow proceeds to step S4. In step S4, the board type confirmation unit 42A displays a change request for the next board type on the display unit 48, and returns the execution of the processing flow to step S1A. The worker who recognizes the change request investigates whether or not the production plan has been changed, and also investigates his / her own setting error. Then, in the second step S1A, the operator places a substrate of a substrate type different from the previous one on the substrate carry-in inlet 21 based on the investigation result.

When the next substrate type is correct in step S3, the substrate type confirmation unit 42A advances the execution of the processing flow to step S5. In step S5, the production condition investigation unit 43A operates following the substrate type confirmation unit 42A. The production condition investigation unit 43 investigates the in-flight condition and collects information on the equipment conditions. In the next step S6, the production condition investigation unit 43A determines whether or not the equipment condition is satisfied.

In the second embodiment, the production condition investigation unit 43A investigates whether or not the member condition and the human condition are satisfied in addition to the equipment condition. Specifically, in step S6A when the equipment condition is satisfied, the production condition investigation unit 43A manages the member condition of whether or not the member necessary for the production of the substrate of the next substrate type is sufficient. Query server 75. In step S6B when the member conditions are satisfied, the production condition investigation unit 43A informs the personnel planning management unit 73 whether or not the number of workers required for the production of the next substrate type substrate is sufficient. Inquire. If any one of the equipment condition, the member condition, and the human condition is not satisfied, the production condition investigation unit 43A advances the execution of the processing flow to step S7.

In step S7, the production condition investigation unit 43A displays a warning display on the display unit 48, and proceeds to the execution of the processing flow in step S8. The worker who recognizes the warning display investigates the unsatisfied conditions, consults with the production manager as necessary, and takes measures to satisfy the above three conditions. Then, after the three conditions are satisfied, the operator inputs a restart command from the input unit 49.

In step S8, the production condition investigation unit 43A waits for the input of the restart command. When the restart command is input, the production condition investigation unit 43A returns the execution of the processing flow to step S1A. If the worker's treatment is short, the production plan is rarely changed. However, if the procedure is long-term, the production plan is often changed. Therefore, in step S1A returned, the operator investigates whether or not the production plan has been changed, and then places the substrate K or another substrate on the substrate carry-in inlet 21.

When the three conditions are satisfied, the production condition investigation unit 43A advances the execution of the processing flow to step S9. In step S9, the production permission unit 44 operates following the production condition investigation unit 43A. The production permission unit 44 permits the production of the next substrate type substrate. As a result, the processing flow of the control unit 4A ends. Subsequently, the setup change work corresponding to the next substrate type is performed to prepare for production. Subsequently, the solder printing machine 12A starts production of a substrate of the next substrate type.

(5. Aspects and effects of the substrate production machine of the second embodiment)
In the solder printing machine 12A which is the substrate production machine of the second embodiment, the substrate type setting unit 41A is a plurality of production job data (JOB1, JOB2) used when producing the substrate of the substrate type from the next time onward, and is the substrate. It holds a plurality of production job data (JOB1 and JOB2) that are different for each type, and selects the production job data corresponding to the next board type according to the automatic selection function. According to this, it is possible to set and confirm the board type from the next time onward by using the production job data different for each board type. Further, since the worker does not set the next board type, the worker's setting error due to a slight difference in the data name and update history information of the production job data does not occur.

Further, the substrate type confirmation unit 42A inquires the set next substrate type to the production order management unit 72 that manages the production order of the plurality of substrate types, and confirms whether or not the setting is correct. According to this, since the production sequence management unit 72, which is the basis of the production plan, is directly inquired, no error occurs.

Further, the production condition investigation unit 43A has a member condition in which the members necessary for the production of the substrate of the substrate type are sufficient, a human condition in which the workers required for the production of the substrate of the substrate type are sufficient from the next time onward, and a human condition. Next, we will investigate the equipment conditions that are in the in-flight state where the production of substrates of the substrate type can be started. According to this, production is not permitted if any of the three conditions are not met. Therefore, if the production plan is changed after this, the substrate type can be reset from the next time onward.

(6. Substrate production line 1B of the embodiment)
Next, the substrate production line 1B of the embodiment will be mainly described as being different from the substrate production machines of the first and second embodiments. FIG. 7 is a diagram schematically showing the configuration of the substrate production line 1B of the embodiment. The substrate production line 1B includes five substrate production machines (12, 13, 14, 15, 16) that share the production of substrates, and a line management device 3. However, each board production machine (12, 13, 14, 15, 16) does not hold production job data, and four functional units (41, 41A, 42, 42A, 43, 43A, 44). I don't have any.

The line management device 3 is configured by using a computer device. The line management device 3 has a display unit 31 and an input unit 32. The line management device 3 is communication-connected to each board production machine (solder printing machine 12, printing inspection machine 13, component mounting machine 14, board appearance inspection machine 15, and reflow machine 16) using a communication line 29. The line management device 3 is also communicatively connected to the administrator terminal 6. Further, the line management device 3 can also access the production database 5 by using the communication line 29.

A plurality of production job data (JOB3, JOB4) are stored in the production database 5. The production job data (JOB3, JOB4) is different data for each type of substrate to be produced. The production job data (JOB3, JOB4) includes five substrate production machines (12, 13, 14, 15, 16) constituting the substrate production line 1B.

The line management device 3 includes a board type setting unit, a board type confirmation unit, a production condition investigation unit, and a production permission unit as four functional units that operate when switching the production substrate type. The four functional units operate in order as in the first embodiment. The board type setting unit holds data names and update history information of a plurality of production job data (JOB3, JOB4). Therefore, the board type setting unit can set the board type from the next time onward by selecting the data name and the update history information. Similar to the substrate type setting unit 41 of the first embodiment, the substrate type setting unit sets the substrate type from the next onward according to the operator's selection operation.

Further, the operation of the substrate type confirmation unit also substantially matches the operation of the substrate type confirmation unit 42 of the first embodiment. The Production Condition Investigation Department investigates whether or not all the substrate production machines (12, 13, 14, 15, 16) satisfy the equipment condition that the production of substrates of the substrate type can be started from the next time onward. do. The production condition investigation unit collects information on the in-flight state of each substrate production machine (12, 13, 14, 15, 16) using communication, and determines the equipment condition. The production license unit produces the boards of the next and subsequent board types by transmitting the production job data corresponding to the next and subsequent board types from the production database 5 to each board production machine (12, 13, 14, 15, 16). Allow to do.

The substrate production line 1B of the embodiment includes a plurality of substrate production machines (12, 13, 14, 15, 16) that share the production of substrates, and a line management device 3, and the line management device 3 is currently produced. A board type setting unit that sets the next and subsequent board types to be produced after the current board type, a board type confirmation unit that confirms whether the set next and subsequent board types are correct, and a next and subsequent board types. The production condition investigation department that investigates whether or not the production conditions for producing the above substrates are satisfied, and all the substrate production machines (12, 13, 14, 15, 16) have the correct substrate type and the production conditions. When is satisfied, a production permission unit that permits the production of a substrate of the substrate type from the next time onward is provided.

According to this, the permission and disapproval of the production of the substrate are determined in the same manner as the substrate production machine of the first embodiment. Therefore, it is possible to deal with artificial setting errors and changes in the production plan, and it is possible to start production after confirming that the board type is correct after the set one. Further, in the substrate production line 1B of the embodiment, each effect described in the first embodiment is similarly generated.

Further, in the board production line 1B of the embodiment, the production permission unit transmits the production job data corresponding to the board types to a plurality of board production machines (12, 13, 14, 15, 16) from the next time onward. After that, it is permitted to produce substrates of the substrate type. According to this, the switching of the substrate type to be produced is performed all at once in all the substrate producing machines (12, 13, 14, 15, 16). Therefore, as compared with the case of switching for each substrate production machine in the first embodiment, the labor of the operator is reduced. Further, the absurdity that the substrate types are different from each other among the plurality of substrate producing machines (12, 13, 14, 15, 16) cannot occur.

(7. Application and modification of the embodiment)
In the substrate production machines of the first and second embodiments, the substrate type confirmation unit (42, 42A) operates before the start of the setup change work, but is not limited thereto. That is, even after the start of the setup change work, if the board type confirmation unit (42, 42A) operates before the start of production of the next board type, erroneous production can be prevented. Further, in the substrate production line 1B of the embodiment, after the production job data is transmitted from the production database 5 to each substrate production machine, the substrate type confirmation unit may operate to prevent erroneous production. Further, in the processing flow of FIGS. 3 and 6, the processing when the inquiry result is incorrect and when the production conditions are not satisfied can be variously modified. The substrate production machine and the substrate production line 1B of the embodiment can be applied and modified in various other ways.
